Yuhui.Zheng 1deeb6dd84 Check socket binding result before doing anything with socket. (This is to address ARG findings.) Breaking the single return rule here, due to precedent violation at line 1039 and 1144. 
prvTransferConnect() now returns:
- pdTRUE: everything's good. pdTRUE = 1.
- -pdFREERTOS_ERRNO_ENOMEM: FreeRTOS_socket() failed. -pdFREERTOS_ERRNO_ENOMEM = -12.
- -pdFREERTOS_ERRNO_EINVAL || -pdFREERTOS_ERRNO_ECANCELED: FreeRTOS_bind() failed. Negative values.

Thus, at line 569 and line 617, needs to check != pdTRUE instead of == pdFALSE.

This commit is done on behalf of Alfred.

Richard Barry 53842d4cac Remove the simple UDP client/server tasks from the MQTT demo as the demo's network connection can be tested more easily just by pinging it. 
Tidy up the iot_config.h header files a little.
